Abstract

Platelet-derived growth factor receptor alpha (PDGFRA) plays essential roles in several malignant tumors. Nevertheless, its clinical function in papillary thyroid cancer (PTC) is still unclear. This study aimed to examine the clinicopathologic implication and potential molecular underpinning of PDGFRA in PTC. Relative PDGFRA expression levels in eight cases of normal thyroid tissue, 15 cases of benign thyroid disease, and 90 cases of PTC were examined by immunohistochemistry (IHC). The prognostic value of PDGFRA was assessed by data mining of The Cancer Genome Atlas dataset. LV-PDGFRA overexpression and negative control CON220 lentivirus vectors were constructed and transfected into a PTC cell line. The capacity for cell proliferation, status of the cell cycle, efficiency of colony-forming, and migration ability of the PTC cells after PDGFRA were detected by multiple assays including methyl thiazolyl tetrazolium, flow cytometry, colony formation, transwell assay, and wound healing. Furthermore, bioinformatics analyses were conducted to determine the potential biologic mechanisms of PDGFRA. Results of IHC showed that PDGFRA expression was significantly upregulated in PTC samples and was associated with an advanced pathologic sta...Continue Reading
